Flier for printing-presses



' UNITED STATES PATENT OFFICE.

JOHN F. JOHNSON AND GEORGE A. OLEMESON, OF MILWAUKEE, WISCONSIN- FLIERFOR PRINTING-PRESSE'S.

SPECIFICATION forming part of Letters Patent No. 374,071, dated November29, 1 87.

Application filed December 4, i886. Serial No. 220,689. (No model.)

To all whom it may concern.-

is a full, clear, and exact description thereof.

Our invention relates to fliers for printingpresses; and it consists incertain peculiarities of construction and combination of parts, to behereinafter described with reference to the accompanying drawings andsubsequently claimed.

In the drawings, Figure 1 represents a sectional view of a portion of aprinting-press having ourinvention applied thereto; Fig. 2, an elevationof our flier; and Figs. 3 and 4, detail views of one of the flier-tapes,illustrating on an enlarged scale the means for securing the pinsthereto.

Referring by letter to the drawings, A represents the feed-table of aprinting-press, B the receiving-cylinder, and 0 one of thedelivery-wheels.

Secured to a cross-brace, D, of the press is a bearing, E, in which isadjustably secured the vertical arm of an angular hanger, F, thehorizontal arm of this hanger having journaled thereto afriction-pulley, G, arranged to impinge against a wheel, H, on an end ofthe shaft I, that carries the delivery-wheels O.

- Our flier-frame is composed of a transverse beam, J, having its endsprovided with suitable journals, K, designed to operate in suitablebearings on the frame of a printing-press, a series of bars, L, arrangedat suitable intervals and having their lower ends secured to thetransverse beam, and a transverse bracepiece, M, connected to said barsnear their upper ends. Operative in bearings a on the bars L, near theirlower ends, is a shaft, N, and the upper ends of said bars are providedwith bearings b for a shaft, 0, that carries a series of pulleys, I,over which and said shaft N travel a corresponding series of endlesstapes, Q. On one end of the shaft 0 is secured a contact-wheel, O, thatbears against the friction-pulley G, and by this means motion iscommunicated to said shaft to give the tapes Q the same speed as thedelivery-wheels, and by having the hanger F adjustable the distancebetween the upper end of the flier and said delivery-Wheels may bereadily regulated to suit the work done on the press, While at the sametime the wear on said frictionpulley is compensated for by adjustingsaid hanger. At suitable intervals pins 0, preferably provided with flatheads, are passed through the tapes and disks d, the latter being ofrubber, leather, or other suitable elastic material and serving to bindupon saidair when the flier is operated to deliver the printed sheets tothe table T, and also to cushion the stroke of said flier on this table.

Any time it is found desirable to retain the rod Sin a fixed positionthe screws 6, that engage the slots f in the bearings It, may betightened.

The printed sheets coming from the delivery-wheels are received on thepoints of the pins projecting from the endless traveling tapes andcarried down thereby when at the proper time the flier is operated toplace said sheets on the table T. The moment the flier is operated todeliver a sheet the wheel 0 is brought out of contact with the pulley G,and hence the tapes Q cease their travel to prevent the sheet from beingcarried too far down up on said flier. The mechanism by which the flieris operated to place the sheets on the table is that commonly employedon printingpresses and too well known to need illustration anddescription in this instance.

To prevent the pins on the tapes from coming against the delivery-wheelsof the press when the flier is returned to its normal position, weprovide the bars L of said flier with buffers g, that come against across-brace, U, of said press, as shown in Fig. 1.

It will be noticed that the only possible bearing for the printed sheetsis on the tapepins, and hence these sheets are delivered to the tablewithout smearing, as is often the case with fliers that receive saidsheets directly, on fingers or permanent tapes.

By the employment of fliers similar to that above described a saving ofsheets is effected, and at the same time the presses are better adaptedto fine work, especially in book or other printing requiring animpression on both sides of said sheets.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. A flier for printing-presses, having a series of traveling tapesprovided with projecting pins, and elastic disks arranged on the pinsadjacent to said tapes, as set forth.

2. A flier for printing-presses, consisting of a frame composed of atransverse beam pro-' vided with journals, arms secured at their lowerends to the beam, and a cross-piece uniting these bars near their upperends, a shaft arranged near to and parallel with the framebearn, anothershaft having its bearings in the upper ends of said bars, a series ofpulleys arranged on the latter shaft, a corresponding series of endlesstapes operative on the pulleys and lower shaft and provided severallywith projecting pins arranged at suitable intervals, a yielding rodarranged on said frame to bear against the tapes, and suitable means forretaining said rod in one position, as set forth. o

3. A flier for printing-presses, consisting of a suitable frame havingan upper and lower shaft journaled therein, a series of pulleys arrangedon the former shaft, and a corresponding series of endless tapesoperative on said 35 pulleys and lower shaft and provided withprojecting pins, in combination with an adjustable hanger carrying africtionpulley, a wheel on an end of the delivery-shaft arranged to bearagainst the frietion-pulley, and a con- 0 tact-wheel on the adjacent endof the shaft that carries the tape-pulleys arranged to impinge againstthe friction-pulley, as set forth.

In testimony that we claim the foregoing we have hereunto set our hands,at Milwaukee, in 5 the county of Milwaukeeand State of Visconsin, in thepresence of two witnesses.
